North America. I have not seen this species and cannot 
place it in any genus ; but Miss Ludlow assured me it is an 
Anopheles. Miss Ludlow sent me the following note :— 
“ A curious little error has crept into the description of this 
mosquito, and has been carried into so many authors that it 
seems as if the easiest way would be for the insect to rearrange 
its markings. 
Wiedemann, in his description (Ausse Europ. Zweifliig, Ins. 
p. 12, 1828), says: ‘Taster braunlich schwartz, Glieder an der 
Wurzel wenig schneeweiss 5 ; but this is, of course, a broad 
generalization, and the words are used loosely. 
Coquillett (Circ. 40, 2nd series, Dept. Agric. p. 4, 1899), makes 
the statement more deflnite : ‘ palpi marked with white at the 
bases of last four joints.’ 
Theobald, quoting this, makes it part of his description. 
(Mon. Cul. of the World, Yol. I., p. 294, 1901.) 
Blanchard (Les Moustiques, Hist. Nat. et Med. p. 171, 1905), 
apparently using the same information says: ‘ Palpes d’un 
noir brunatre, marques de blanc a la base des 4 derniers 
articles.’ 
Felt. (Mos. or Col. of N.Y. State, N.Y. State Museum, p. 270, 
1904) also carries on the error, giving as one of the distinctive 
characteristics, c the white bases of the last four segments of the 
palpi.’ 
Smith, in his synoptical Table (Report on Mosquitoes, 
N.J. Agri. Expt. Sta. p. 152, 1904), makes the ‘palpi white- 
marked. at base of joints,’ but figures and describes the palpi 
correctly (id. p. 170). 
Coquillett, in his last work on the subject (a Classification of 
the Mosquitoes of North and Middle America, p. 12, 1906), drops 
this characteristic, but does not correct his former error. 
In reality, the specimens sent in to this office, for more than 
a year, from various parts of the U.S., and those in the collection 
of the National Museum show the last joint of the palpi entirely 
ipwhite (silvery-grey), and very narrow white bands at the bases 
<pf the penultimate and antepenultimate joints, the remainder of 
fehe palpi being entirely brown. The only variation on this is
